PURPOSE: Nitric oxide (NO) exerts the relaxant effect in vascular smooth muscle cells (VSMC) by activating soluble guanylate cyclase (sGC), which produces cyclic guanidine monophosphate (cGMP) in the cell. This study was undertaken to investigate the mechanism of the inhibitory actions of sGC inhibitors, LY 83583 and methylene blue in the VSMC. METHODS: VSMC was primarily cultured from rat aorta and confirmed by immunocytochemistry of anti-smooth muscle myosin antibody. Bacterial lipopolysacchride (LPS), an inducer of inducible nitric oxide synthase (iNOS) and sodium nitroprusside (SNP), an NO donor, were uesd to increase NO within VSMC. The changes in concentrations of nitrite in culture media by an addition of LPS or SNP with a pretreatment of LY 83583 or methylene blue were measured by the spectrophotometry with griess regent and absorbance at 550 nm. Western blot and RT-PCR for iNOS and iNOS mRNA, respectively were performed. RESULTS: LPS and SNP increased nitrite concentration. LY 83583 potentiated the increase in nitrite concentration by LPS and SNP. LY 83583 also increased expressions of iNOS protein and mRNA induced by LPS. Methylene blue has no effect on nitrite concentration increased by LPS or SNP, and it did not affect the expressions of iNOS protein or mRNA induced by LPS. CONCLUSION: These results suggest that the mechanism of inhibitory actions of LY83583 and methylene blue on sGC are different each other: LY83583 interferes the interaction of sGC and NO resulting positive feedback increase in iNOS gene expression, but methylene blue eliminates NO from cytosol inducing no compensatory effect.

In Korea the system of medical management has been bifurcated into two parts since the restoration of nation from Japanese after World War II. One is 'Western Medicine' and the other is 'Oriental Medicine' like Chinese but not like Japanese. The authors attempted to study on the unification of both medicines to prevent the confusion of medicare for people. The major part of medical care is accomplished by Western medicine among people in Korea and China. However, Oriental medicine is still present as well as college of Oriental medicine in small number. There have been long struggles between two parts of medicine because of each assertions for the theories. The ancient medicine has been likely to have its characteristics either in Western or Oriental medicine although in many countries were succeeded by Western medicine except a few Asian countries such as Korea and China. In Japan since the license of Oriental(herb) medicine was ceased about one hundred years ago, the Western medicine has been authorized by law until today and the herb is the secondary medicine as a kind of folk treatment as well as continuous and enormous study for scientification. In only China and Korea this herb medicine has been kept to use as a part of medicine by law though China has developed combined medicine to use both Western and Oriental medicine by one physician since previous prime minister Chou En-Lai around the year 1950 who made a recommendation to the two medical societies, Western and Oriental. This fact has a big sense to establish the unification of two medicines in near future in Korea as well as China. For this accomplishment of medical unification both parts of medicine require sincere and enormous efforts to study the theory and practice of herb medicine even from now on. This unification of two medicines will provide the best medicare in most convenient way to the people in the world creating new world medicine like the third medicine including alternative medicine. The acupuncture is changing to a new method in Western medicine especially applying into anesthesia and pain clinic in even USA and Western countries at this time. In conclusion the unification of the Western and Oriental medicine will provide the most reasonable and practical medicare including alternative medicine to people in the world. Because the Oriental medicine will be used at least separately to supplement the Western medicine by one physician

The typical radiographic findings of pulmonary edema from the increased hydrostatic pressure shows centrally localized consolidation, which is known as a "butterfly or bat's wing" pattern. These terms describe the anatomic distribution of edema that uniformly involve the hilum and medulla of the lung but not the peripheral region of the lung parenchyma (cortex). We present a case of butterfly wing-like pulmonary edema on a chest radiograph by mitral regurgitation due to an idiopathic chordal rupture.

Human Q fever, a zoonosis caused by Coxiella burnetii, presents with diverse clinical manifestations ranging from mild self-limited febrile illnesses to life-threatening complications such as endocarditis or vascular infection. Although acute Q fever is a benign illness with a low mortality rate, a large-scale outbreak of Q fever in the Netherlands led to concerns about the possibility of blood transfusion-related transmission or obstetric complications in pregnant women. Furthermore, a small minority (< 5%) of patients with asymptomatic or symptomatic infection progress to chronic Q fever. Chronic Q fever is fatal in 5–50% of patients if left untreated. In South Korea, Q fever in humans was designated as a notifiable infectious disease in 2006, and the number of Q fever cases has increased sharply since 2015. Nonetheless, it is still considered a neglected and under-recognized infectious disease. In this review, recent trends of human and animal Q fever in South Korea, and public health concerns regarding Q fever outbreaks are reviewed, and we consider how a One Health approach could be applied as a preventive measure to prepare for zoonotic Q fever outbreaks.

Purpose: Alpha-fetoprotein (AFP) is a prognostic marker for hepatocellular carcinoma (HCC). We investigated the prognostic value of AFP levels in patients who achieved complete response (CR) to transarterial chemoembolization (TACE) for HCC. Materials and Methods: Between 2005 and 2018, 890 patients with HCC who achieved a CR to TACE were recruited. An AFP responder was defined as a patient who showed elevated levels of AFP (>10 ng/mL) during TACE, but showed normalization or a >50% reduction in AFP levels after achieving a CR. Results: Among the recruited patients, 569 (63.9%) with naïve HCC and 321 (36.1%) with recurrent HCC after complete resection were treated. Before TACE, 305 (34.3%) patients had multiple tumors, 219 (24.6%) had a maximal tumor size >3 cm, and 22 (2.5%) had portal vein tumor thrombosis. The median AFP level after achieving a CR was 6.36 ng/mL. After a CR, 473 (53.1%) patients experienced recurrence, and 417 (46.9%) died [median progression-free survival (PFS) and overall survival (OS) of 16.3 and 62.8 months, respectively]. High AFP levels at CR (>20 ng/mL) were independently associated with a shorter PFS [hazard ratio (HR)=1.403] and OS (HR=1.284), together with tumor multiplicity at TACE (HR=1.518 and 1.666, respectively). AFP non-responders at CR (76.2%, n=359 of 471) showed a shorter PFS (median 10.5 months vs. 15.5 months, HR=1.375) and OS (median 41.4 months vs. 61.8 months, HR=1.424) than AFP responders (all p=0.001). Conclusion High AFP levels and AFP non-responders were independently associated with poor outcomes after TACE. AFP holds clinical implications for detailed risk stratification upon achieving a CR after TACE.
